A problem could be, how can I answer anonymously to someone who didn't reveal his DRK address?
Meaning: how can I answer anonymously to someone anonymous?
Suppose I let someone buy a product anonymously on my website. So he just payed me some DRK anonymously, and now expects me to send him a serialnumber or something.
But I do not know his send address, because he used Darksend.
I would have to insist that he gives me atleast some kind of information (or not use darksend), so I know where to send the serial number, right?
So together with the anonymous payment he would need to send me his email- adress or something, or his anonymous DRK mail account, or whatever, so I can know where to answer....
